This short article by Shawn Nevers, a law librarian at BYU, appearing in the current edition of the ABA Student Law Journal exhorts readers to take a course in advanced legal research before they graduate. You'll find no argument with that here.

Most law schools offer some sort of advanced or
specialized legal research course as an elective. Take it! Take it even
if you don’t love legal research. Especially take it if you’re not good
at legal research. You will soon be doing research on someone else’s
dime. Why not get ready for it?

Most, if not
all, advanced legal research classes are taught by law librarians. They
are expert researchers who know about the latest legal resources and can
teach you a lot about the legal research process. You’ll also get the
chance to do a lot of research, which is critical to becoming a good
researcher. If you don’t practice researching now, you’ll be doing it at
your job, which is where you’d be better off impressing than learning.

Abraham
Lincoln’s quip about a book he read could easily be applied to legal
research—“People who like this sort of thing will find this the sort of
thing they like.” The truth is, however, that whether you like it or
not, legal research is a critical part of lawyering. Don’t underestimate
its importance.
